Savor an exquisite harmony of
sensations and emotions

A selection of choice ingredients, imaginative new dishes, and attentive service...offering a perfect time and place for people to come together in a world all its own.
The name “Rikki” symbolizes the six essential energies connecting heaven and earth that give form to nature. It also refers to the six emotions of love and hatred, pleasure and anger, grief and joy.

The harmony of these sensations and emotions, the interweaving of people and nature, gives birth to an infinite world of new flavors.
Here at this culinary laboratory, Chef Yoshiaki Kogawa of the renowned Kamakura Heritage Koga Residence works with the local people and environs of Hagi to explore new culinary possibilities and create unique taste sensations.

Hagi is a port city located on a river delta, a nexus of river and sea, mountains and quiet hamlets. With lush natural surroundings and a centuries-old history of flourishing trade, Hagi is the ideal locale for sourcing the finest culinary ingredients. Abundant marine products from the Sea of Japan, authentic wagyu beef, and fruits and vegetables nurtured in rich fertile soil are all of the finest quality. This treasure trove of ingredients is every chef’s dream.



The quality and flavor of the marine products at Hagi Port attract seafood wholesalers from throughout Japan. Highly sought after by purveyors of haute cuisine, such exceptional ingredients are found right on Rikki’s doorstep. This geographical advantage and Chef Kogawa’s network of local producers ensure that guests enjoy an unparalleled selection of exquisite seafood.


For an exclusive taste experience, Japanese Polled — the rarest breed of wagyu beef cattle — is purchased directly from Japan’s sole producer, the Japanese Polled Public Corporation. With a high lean meat content and distinctive Wagyu taste, only the meat from just two head of cattle is available each month. Guests can also enjoy wild game from autumn through winter, including an occasional wild boar supplied by local hunter Kazunori Arida.


As head chef at the Kamakura Heritage Koga Residence, Chef Kogawa grows his own vegetables, paying special attention to them as they ripen. Now, together with local Hagi farmer Takaya Umeji and Minoru Farm’s Minoru Hosoda, Chef Kogawa is opening the door to an unprecedented palette of novel flavors and taking on new challenges in collaboration with professionals in both agriculture and the culinary arts.


Yoshiaki Kogawa


I see my role as a bridge between the producers of food and the people who consume it, bringing out the full potential of the ingredients in new ways.
By exploring novel combinations and fusing distinctive flavors, we are creating original cuisine found nowhere else. I’m confident we will discover new flavors that even I can’t imagine.

The highest quality vegetables, meat, and fish can be found here in Hagi, thanks to the pride and care of each local producer. Working closely with such people ensures the restaurant’s food will be delicious.
Ingredients from the same season and locality go best together. For example, locally produced Hyakusho-an natural salt has an appealing mellow taste flavored by the mixture of marine and mountain minerals found in the waters of Yuya Bay. Its taste changes with the seasons, and each season’s salt perfectly matches that season’s vegetables.


It’s a pleasure for me to experience such discoveries and feel the deep connections, so I want to continue moving forward guided by the inspiration that comes from this interplay of people and place. Together with Hagi’s residents and visitors, I want to enjoy that new world as it opens up before us. This is a venue for discovery and creativity that inspires the imagination. I hope you will come and join us in our unique adventure.
